Factor 1.21a^6+22a^3+100

Monica [59]

Answer:

$\frac{1}{100} (11 {a}^{3} + 100)(11 {a}^{3} + 100)$

Step-by-step explanation:

$1.21 {a}^{6} + 22 {a}^{3} + 100 \\ = 1.21 {a}^{6} + 11 {a}^{3} + 11 {a}^{3}+ 100 \\ = 11 {a}^{3} (0.11 {a}^{3} + 1) + 100(0.11 {a}^{3} + 1) \\ = (0.11 {a}^{3} + 1) (11 {a}^{3} + 100) \\ = ( \frac{11}{100} {a}^{3} + 1) (11 {a}^{3} + 100) \\ = ( \frac{11{a}^{3} + 100}{100} ) (11 {a}^{3} + 100) \\ = \frac{1}{100} (11 {a}^{3} + 100)(11 {a}^{3} + 100) \\ are \: the \: required \: factors.$

Craig bought a treadmill for $400. He estimates that the annual costs to maintain the machine will be $36. Which rational functi

Lorico [155]

Given that Craig bought a treadmill for 400 dollars.

Useful life of the macine = x

Hence annual purchase cost spread over x years will be 400/x per year.

In addition, there is an annual maintenance cost of 36 dollars.

Hence Average annual cost in dollars = purchase cost per year+maintenance cost per year

= $\frac{400}{x} +36 \\= \frac{400+36x}{x}$

Hence answer for rational function is

either $\frac{400}{x} +36[tex]Or [tex]\frac{400+36x}{x}$
